I have integrated the GAEMA code gaema with web2py to allow my sites to authenticate via Google, Twitter, and/or Facebook.
I modified the module very slightly and collapsed it into a single file - auth_base.py. From there I created the classes for Facebook, Twitter, and Google authentication. The auth_base.py file supports Friend Feed and perhaps other things that I was not interested in, so I did not implement them yet.
download the module files here authmodules.tgz
To use the modules, make sure that your auth_user table has both username and email in the fields. Twitter and Facebook don't provide email address in their callback, so they use username. Google uses the email field. (I suppose it would be easy to make Google use username as well). For Twitter and Facebook the username that I create is "Twitter_<uid>" or "Facebook_<uid>". I have considered creating a custom auth.get_or_create_user() method to allow the same user to associate multiple account types with a single auth_user record, but don't yet have use for that.
To use the auth modules, consider a controller something like:
def index():
retval = dict()
retval['twitter'] = A('Login Via Twitter', _href=URL(r=request, c='authtest', f='twitter'))
retval['facebook'] = A('Login Via Facebook', _href=URL(r=request, c='authtest', f='facebook'))
retval['google'] = A('Login Via Google', _href=URL(r=request, c='authtest', f='google'))
return retval
def twitter():
if auth.is_logged_in():
redirect(URL(r=request, c='default', f='index'))
from applications.ec.modules.twitter_account import TwitterAuth
auth.settings.login_form=TwitterAuth(request, response,
**{
'twitter_consumer_key':'<your key here>',
'twitter_consumer_secret':'<your secret here>',
'globals':globals()})
return auth.login(next=URL(r=request, c='default', f='index'))
def facebook():
if auth.is_logged_in():
redirect(URL(r=request, c='default', f='index'))
from applications.ec.modules.facebook_account import FacebookAuth
auth.settings.login_form=FacebookAuth(request, response,
**{
'facebook_api_key':'<your key here>',
'facebook_secret':'<your secret here>',
'globals':globals()})
return auth.login(next=URL(r=request, c='default', f='index'))
def google():
if auth.is_logged_in():
redirect(URL(r=request, c='default', f='index'))
from applications.<appname>.modules.google_account import GoogleAuth
auth.settings.login_form=GoogleAuth(request, response,
**{'globals':globals()})
return auth.login(next=URL(r=request, c='default', f='index'))
Update 2010-May-04
Facebook released the Graph API, and announced the end of FacebookConnect, so I did some rejiggering. the updated code is now an hg repository here: web2py_multiauth. The updated version also merges accounts if the user has the same email with a twitter login and facebook login for example. see the README file in the code for installation and configuration instructions.

in theory most of the stuff should work.....there is an outstand patch submitted to the repo that i just noticed. i wouldn't be suprised if it is broken though given that facebook and twitter have changed things over the years.
the project i used this for is no longer supporting multiple authentication types, so i'm not actively user the code. :(

updates: seems that the "perms" parameter changed to scope: fblogin = function() {FB.login(function(response) { if (response.session) { window.location='{{=URL(r=request, c='auth_ext', f='facebook')}}' } else { // user is not logged in //window.location='{{=URL(r=request, c='auth_ext', f='denied')}}' console.log('falha') } }, {scope:'email'});}; Still not works, maybe response.session is wrong?
